Multi-copy routing method have considered the most applicable way to deliver the message in Delay Tolerant Networks. They allow multiple message copies to be sent in order to increase the message delivery ratio or reduce its delay. The efficient message scheduling method to determine which messages should be dropped and which should be forwarded if buffer is full. In this paper examine a novel message scheduling framework for two-hop forwarding and epidemic routing in delay tolerant networks , such that node can take the dropping and forwarding decision during each contact for either optimal message delivery ratio or message delivery delay. The proposed scheduling framework can achieve superb performance against its counterparts in terms of delivery delay.
